Goal Zero Yeti 400 running a Harbor Freight 100 psi air compressor and charging a Kindle Fire while being charged with a HQST 100 watt solar panel. The Yeti was full and the compressor was empty. The compressor took about 4 minutes to fill. The battery level on the Yeti did not drop, although it continued to take charge for several minutes after the compressor stopped. The panel put out a max charge of 77 watts, which isn’t too bad for March in the Pacific NW of the USA.
